Mod name: No Hostiles Around Campfire
Mod version: 1.16-2.3

I have a bunch of soul campfires placed around. They don't seem to be working very well. If I place a new one, it burns the things around it, but they aren't preventing new spawns at night. And when new things spawn, they can be near the campfire with impunity. I tested if it was because they were off the ground for some reason, and that doesn't seem to be it.

You can see these guys here aren't being hurt by it. They spawned after the fire was started.
I'm about to test if regular campfires also have that issue. Edit: they also don't work right.

Also, these should prevent Pillager raids spawning in their radius, right? Do you happen to know if it stops raids entirely, or just causes them to spawn outside the campfire radius? I haven't had one happen yet.

Thanks for opening the issue and using the mod! This should be fixed in version 2.4. The distance was calculated wrong, and should work as intended now.
